.pyc files contain modification time of .py source. In order to make build reproducible, we fix modification time of all .py before to compile .pyc files. In order to guarantee .pyc are regenerated regardless their modification time, we remove .pyc before to compile. However, I wonder if it wouldn't be simpler to always call compile_all with 'force' flag. This work was sponsored by `BA Robotic Systems'.
